Studies on boron compounds XX:Synthesis and conversion of ethanolamine tri92-furyl)borane

Abstract

Reaction of 2-furyllithium with (N,N-diethylamino)dichloroborane gave the title compound (I). By acidifying I, tri(2-furyl)borane was liberated, which reacted with pyridine to yield pyridine-tri(2-furyl)borane. A furyl group at I could be cleaved by 8-hydroxylquinoline or 8-hydroxyquinaldine in the presence of dilute HCl and yielded (8-quinolyloxy)difurylborane or (8-quinaldyloxy)difurylborane containing intramol. B-N coordination bond.

Key words: PYRIDINE P, AMINES, FURAN P, ETHANOL P, BORANES, ORGANO BORON COMPOUNDS

CLC Number:
